Description
Lepton flavor violation in neutrinos aka neutrino-oscillation is a telltale signature of Beyond the Standard Model (BSM) physics. If a similar phenomenon is found in the charged leptons as well, that will further consolidate the existence of BSM physics. In this work, we look for signature of charged lepton flavor violation (CLFV), muon to tau conversion, in the IceCube. We focus on two main scenarios: (a) CLFV interactions described by Effective Field Theory (EFT) operators and (b) the BSM mediator of such charged lepton flavor violating interaction being an axial-vector $Z'$. We set a constraint on the relevant new physics energy scale of the EFT operators and on the parameter space of $Z'$ from the analysis of the existing IceCube data. We compare our obtained constraint to that from collider experiments as well. Moreover, we predict a plausible constraint from two specific future generation experiments, IceCube-Gen2 and HUNT.
